wireless card not working with ubuntu 11.10

[amvb]

After having Windows 7 crash on me all the time, and getting tired of it, I wound up turning to Ubuntu for my laptop. I have Ubuntu 11.10 on there running fine, but my wireless internet wont work. Wired does; just not wireless. I've found other people with this problem, but nothing I've found seems to help. All the threads I've found in places are either unanswered or the conversation stopped abruptly. (Another random problem to tack on that I just noticed: when I close my laptop with Ubuntu running and open it back up, the screen is black and I have to manually shut it down and restart it.)
My wireless card is a Ralink rt3090 and I'm using a Lenovo B575.
Thanks a lot!!!
